Thank you, I did find some carriage returns within footnotes. I deleted those and reran the macro as above and still got the same error message.

The only other way that I can think of a type 13 error would occur is if you've got anything other than a space after your footnote number in the footnote text.

For example:
1 adhidnads in asdifnidsfn

Will work well but:
1] asdnin idsne i sdf
or
1A. Schwarzenegger asdinvie dinsve
will create a type 13 error.

The macro does provide for ways of removing standard formatting (such as going from [1] -> 1) but my pdf conversion isn't consistent about spacing so I've had a situation where the space after the footnote number disappeared and it threw everything off. Might that be what's happening to you?

Do you have a space character after each footnote reference in the document body? As the notes in post 2 indicate, that is a requirement.

Yes, I did ensure there's a space character after each footnote reference in the document body.
